Colorado Air and Space Port serves the Denver-Aurora-Lakewood, CO Metropolitan Statistical Area. The postal designation of Watkins, a nearby unincorporated community, is used in the airport's mailing address.

Colorado Air and Space Port ICAO/FAA identifiers are KCFO/CFO. The airport has no IATA designation.

Colorado Air and Space Port is a small general aviation airport, although increased demand has warranted several expansion programs in recent years. Currently, the airport serves as the base of a few flying schools, flight clubs, maintenance services, and air rescue training facilities. Due to its location on the flat plains of eastern Colorado, as well as generally cheaper aircraft rental rates, it is a very popular airport for both flight training and recreational flights. It is also popular among owners and pilots of kit-built aircraft, and the Experimental Aircraft Association (EAA) has a very strong presence at Colorado Air and Space Port, which frequently hosts the EAA Young Eagles Rallies.

In 2011, the State of Colorado applied to the FAA to certify Colorado Air and Space Port as a spaceport.
